This is it. IC², the future of IC.
While playing it, you will feel right at home again, rediscovering most of the stuff known from IC. However, once you get your machines running, you will quickly notice how smooth and well-designed everything works now. Wiring is easier, batteries aren't as two-sided (on/off) anymore, new cables, rubber stuff, new machines, EVERYTHING was added.
Create obstacle courses of Metal Poles and Rubber-Sheets, explore the Nether with an Electrical Jetpack or blow up whole landscapes at once by using the Dynamite-O-Mote. Or discover the much more complex mechanisms of Nuclear Engineering, blow up your hut or burn your hands. Or grab the rusty ol' Composite Vest, and start hunting Creepers with the new, almighty Nano Saber.

v1.108[r2] - The Slightly Derpy Update
#Added: Missing block_machine2.png to 512x and 256x

v1.108 - The Pretty Pointy Update

The issue I'm having is that the iron furnace is showing up as a pink/black jumbo of nasty - i haven't taken a look myself but it may be just a simple incorrect spacing in the png? Now that I really look, I guess I don't see a texture at all for it.

Edit: After looking - I have absolutely no idea even what file this GUI is from - but it's an IC2 block - I even looked in an older version to see if I could find it but it's just missing - weird.

It is not a problem of texturepacks, but inner problem of IC2_lf_401 itself. As well, as problems with textures of IC2 armors. You could handle this wisiting [email protected] forum, and seeking out thread for this problem, somewhre in "support"
The problem allready solved in Ic2_experimental. Still, there is a lot of others... )

If you having troubles with textures, first - take off resourcepacks and make sure, it is a resourcepack problem. Later, it'll could be a real shame, if it not.... )

I was genuinely excited someone had engaged for once instead of just demanding updates, but sadly your concept is like the lazy stuff pcmaster and myself did for GregTech for the on/off (or was it low/high stuff?).

I'll take a crack at updating IC2 properly this weekend.

Hopefully get a tidier solution to the energy boxes. I already have a fuzzy idea about them. We shall see.
